PK-3 30g
by Paul BennettWas going to give a 3-4, because its not that easy to apply & cost the earth, but this stuff is VERY GOOD at what it does, my idle temp is down 3deg to 27* and a quick load is down 6deg to 45*, compered to my old good quality white silicone, Seems to need a day to bed in to get the best result.Thx Paul
